The Subway Trail
In order to hike the subway trail, hikers need a PERMIT from the administration of Zion National Park that can be picked up from the visitor center. This is day-use only hike.
The Subway Trail can be accessed off of Kolob Terrace Road at the Left Fork Trailhead.
The trail gets its name from the pipe-like gorge formed by the canyon walls of North Creek. This is a canyoneering tour through the left fork of North Creek. It is a long day hike to dinosaur tracks, keyhole falls, and the subway. The trail follows a the creek and hikers have to pass through creek in many locations along the hike. The trail is not maintained.
It is recommended that you are either an experienced hiker or have an experienced hiker to guide you on this slot canyon trail, as unlike the Narrows, it is a semi-technical hike that can require rappelling and swimming through deep pools of cold water. The subway section of the trail can also be very slippery so proceed with caution.
This hike starts from the bottom of the Subway Trail, however many hikers do this trail from the top down off of Wildcat Canyon Trailhead, as the bottom up route is much more difficult. This area can be prone to flash floods so be mindful of rain and talk to park rangers before heading out on your hike if you have any concerns.
